Microvascular Endothelial Cells
Endothelial Cell Biology
Small blood vessel function and tone is regulated by critical components of the vessel wall including cellular components such as the endothelium and the vascular smooth muscle cells and structural components such as collagen and elastin fibres. Our research focuses on the molecular basis of vascular/endothelial changes in pathological conditions such as diabetes and cancer metastasis.
The main research focus of my group is endothelial cell biology; more specifically the role of changes in the endothelium of small vessels in diabetic microangiopathy and tumour metastasis. We isolate and/or culture several types of mammalian endothelial cells, including microvascular endothelial cells from the retina, brain and omentum. This allows us to study, in vitro, disease-specific models utilizing endothelial cells from relevant vascular beds.
